CHMO, the chemical methods ontology, describes methods used to collect data in chemical experiments, such as mass spectrometry and electron microscopy prepare and separate material for further analysis, such as sample ionisation, chromatography, and electrophoresis synthesise materials, such as epitaxy and continuous vapour deposition It also describes the instruments used in these experiments, such as mass spectrometers and chromatography columns. It is intended to be complementary to the Ontology for Biomedical Investigations (OBI).

The height of the peak is proportional to the defect density and the emission rate and temperature dependence are characteristic for each type of defect. https://orcid.org/0000-0001-5985-7429 2009-05-20T11:15:51Z I-DLTS IDLTS current DLTS current-DLTS CHMO:0001773 current deep-level transient spectroscopy A method for determining the extent of intrinsic and process-induced defects in the crystalline layers within semiconductor devices.

The distance between the probe and sample is kept constant during the measurement using a feedback loop. https://doi.org/10.1007/s003390051144 An image obtained by using a sharp spike (known as a 'tip') mounted on the end of a cantilever to scan the surface of the specimen, line by line, and recording the difference in work function between the tip and sample as a function of position. https://orcid.org/0000-0001-5985-7429 2009-09-24T04:44:44Z KPFM image CHMO:0002460 Kelvin probe force micrograph An image obtained by using a sharp spike (known as a 'tip') mounted on the end of a cantilever to scan the surface of the specimen, line by line, and recording the difference in work function between the tip and sample as a function of position. https://orcid.org/0000-0002-0640-0422 A two-dimensional separation method where the separation processes are both capillary electrophoresis. https://orcid.org/0000-0001-5985-7429 2009-09-25T10:16:34Z 2D CE 2D-CE CE-CE CE/CE CHMO:0002461 two-dimensional capillary electrophoresis A two-dimensional separation method where the separation processes are both capillary electrophoresis. https://orcid.org/0000-0002-0640-0422 A two-dimensional separation method where the sample is first subjected to liquid chromatography followed by capillary electrophoresis. https://orcid.org/0000-0001-5985-7429 2009-09-25T10:18:22Z LC-CE LC/CE CHMO:0002462 liquid chromatography-capillary electrophoresis A two-dimensional separation method where the sample is first subjected to liquid chromatography followed by capillary electrophoresis. https://orcid.org/0000-0002-0640-0422 An ionisation method where the sample is either forced through a small heated capillary (at a flow rate of 1–10 L min-1) into an electric field to produce a very fine mist of positively charged droplets, or solvent droplets subjected to the same process are directed at the sample. https://orcid.org/0000-0001-5985-7429 2009-09-28T11:46:03Z +ESI positive electrospray ionization CHMO:0002463 positive electrospray ionisation An ionisation method where the sample is either forced through a small heated capillary (at a flow rate of 1–10 L min-1) into an electric field to produce a very fine mist of positively charged droplets, or solvent droplets subjected to the same process are directed at the sample. https://orcid.org/0000-0002-0640-0422 An ionisation method where the sample is either forced through a small heated capillary (at a flow rate of 1–10 L min-1) into an electric field to produce a very fine mist of negatively charged droplets, or solvent droplets subjected to the same process are directed at the sample. https://orcid.org/0000-0001-5985-7429 2009-09-28T11:47:32Z -ESI negative electrospray ionization CHMO:0002464 negative electrospray ionisation An ionisation method where the sample is either forced through a small heated capillary (at a flow rate of 1–10 L min-1) into an electric field to produce a very fine mist of negatively charged droplets, or solvent droplets subjected to the same process are directed at the sample. https://orcid.org/0000-0002-0640-0422 The sedimentation of a solid material (a 'precipitate') from a liquid solution caused by the addition of an additional different solvent. https://orcid.org/0000-0001-5985-7429 2009-09-28T11:52:22Z CHMO:0002465 solvent precipitation The sedimentation of a solid material (a 'precipitate') from a liquid solution caused by the addition of an additional different solvent. https://orcid.org/0000-0002-0640-0422 The sedimentation of a solid protein (a 'precipitate') from an aqueous solution caused by the addition of an organic solvent (e.g. methanol), a polyelectrolyte (e.g. alginate) or a salt (e.g. ammonium sulfate) in a process known as 'salting out'. https://orcid.org/0000-0001-5985-7429 2009-09-28T11:55:08Z CHMO:0002466 protein precipitation The sedimentation of a solid protein (a 'precipitate') from an aqueous solution caused by the addition of an organic solvent (e.g. methanol), a polyelectrolyte (e.g. alginate) or a salt (e.g. ammonium sulfate) in a process known as 'salting out'. https://orcid.org/0000-0002-0640-0422 The component of a system to be analysed. https://orcid.org/0000-0001-5985-7429 2009-09-29T11:58:40Z CHMO:0002467 analyte The component of a system to be analysed. https://doi.org/10.1351/goldbook.A00331 true The liquid or gas entering a chromatographic column and used to effect a separation by elution. https://orcid.org/0000-0001-5985-7429 2009-09-29T12:01:03Z CHMO:0002469 column eluent The liquid or gas entering a chromatographic column and used to effect a separation by elution. https://doi.org/10.1351/goldbook.E02040 Microscopy where an electron-transparent specimen is bombarded with a finely focused (<10 nm diameter) electron beam with an acceleration voltage 50–150 kV. under vacuum.
